In her ongoing quest to remind us that she's no longer Hannah Montana, Miley Cyrus twerked and gyrated her way through Sunday night's performance of her hit single, "We Can't Stop," and subsequent duet with a relatively subdued-looking Robin Thicke.

Flanked by life-size teddy bears, Cyrus first took the stage in a fuzzy gray unitard that showed off her long legs and twerking skills. After singing "We Can't Stop" -- during which the word "molly," a supposed drug reference, was bleeped out -- the 20-year-old singer stripped down to nude underwear before grinding up and down Thicke during his rendition of "Blurred Lines."

Miley's grown-up performance stunned both the Twittersphere and the Barclays Center audience. Celebrities and other social media users took to Twitter to discuss Cyrus' raunchy dance moves, while many shared screen grabs of famous members of the audience looking aghast -- including the boys of One Direction and Will Smith's entire family.
